To all whom, it may concern:

Be it known that I, FRANZ WIELAND, a subject of the King of Prussia,German Emperor, residing at Berlin, in the Kingdom of Prussia, GermanEmpire, have invented certain new and useful Improvements in Pestles andsquashing Apparatus, of which the following is a specification.

The invention has been patented in Germany September 9, 1894:, No.82,418; in Switzerland December 5, 1894, No. 9,579; in Belgium October19, 1894, No. 112,318; in France October 19, 1894, No. $12,225, and inAustria October 12, 1894, No. 45/1,135.

The object of this invention is the construction of a pestle, either byitself or in combination with a squashing apparatus, which facilitatesthe squashing of soft plastic materials and the forcing them through asieve, distinguished from the usual pestle by having its lowerball-shaped end united, with the handle by means of a socket-joint. Inconsequence of this joint connection the ball has its own separatemotion, feeding continually fresh material. I

In the drawings, Figures 1, 2, and 3 show difierent combinations betweenball and handle, while Figs. 5 to 8 show the construction of thesocket-joint which connects the ball with the handle. Figs. 1 and 10represent the combination of the improved pestle with a squashingapparatus and the pivoting of the pestle in two different constructions.Fig. 9 is a detail of Fig. 10.

The improved pestle consists of the handle a and the ball cl, the latterbeing connected to the former by means of a joint, allowing the ball anindependent motion from the mo- The joint connection of ball cl withhandle a may consist of a sleeve 1), Figs. 1 and 2, connected with thehandle a by means of the pin 0 or of a socket-joint of, Figs. 3, 5, and6. There may be also a combination of socket-joint and sleeve, as shownin dotted lines, Fig. 2, in such a manner that the sleeve does notencompass the ball, but is fitted at each end with a socket-joint, whichis connected with the balls. Thesleeve b may in this case be rigidlyunited with the handle, Fig. 5, or pivoted by means of pin 0, Fig. 1.

In operation the pestle is either pressed in the usual manner againstthe material (such as boiled potatoes) in the basin l3, forcing itthrough the perforated bottom E, or the basin B may be in combinationwith a steaming vessel 0, Fig. 4. The bottom of basin B is a concavesieve E, which enters the top part of the boiling-pot O, which lattercontains water and is put on the fire. Into the cover D of basin B iscut a central hole, into which opening the handle of the pestle isintroduced, either direct or in combination with ball g, Fig. 4, throughwhich the handle of the pestle passes. The ball 9 is held in its placeon the cover by bearing-plate It.

By using the socket-joint for the connection of ball 61 and handle a thedisjointing of the two parts is easily effected, which is of importancefor the purpose of cleaning the pestle.

Figs. 5 to 8 illustrate the construction of the socket-joint. Thesocket-joint consists of a ball 6, inserted into the lower end of thehandle a, moving in the bearing-platef, fixed to the squashing-ball cl,Fig. 5, by means of screws Z, Fig. 8. The plate f has in its center aconcave recess for the reception of ball 0 and is fitted withprojections or lugs 1', entering slots 2' in the top plate f, whichencircles the upper half of ball 6. The lugs i have at their top endshooks or buttons. If the two plates f and f are united, the lugs 4."enter into the slots 2'. The top plate is then turned a short distance,the hooks grasp the plate, and the connection is completed. Theconnection may also be made in such a manner that the hook or buttonheaded lugs t" are pivoted to the plate f, and by making the connectionthe plates are brought in such a position that the lugs 2" enter theslots '5, projecting with their heads over the top plate f. The lugs arenow turned, so that the hookshaped heads stand in a right angleto theslot, and the connection is completed. It is evident that the takingapart of ball and handle for the sake of cleaning is, according to thisconstruction, a matter of ease and convenience.

Figs. 9 and 10 show a modification of the connection of the pestle withthe cover of basin B by means of two balls g g, connected with eachother by a tube 7a, through which tube the helve of the pestle (which isin this case round, suiting the size of the tube) is passed and thehandle screwed on the top. The cover, with a hole in its center, isplaced between the two balls, giving the pestle free play for moving inany direction, while the tube 70 permits the lowering and raising of thepestle.

I claim- 1. In combination, a pestle comprising a stem and a lowerspherical part or ball and a swiveled connection uniting the stem andball, substantially as described.

2. In combination, a pestle comprising a stem and a lower sphericalpartor ball, a ball on the end of the stem fitting a socket in thespherical part and means for securing the stem and sphere together,substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
